Depending on how much user input is needed in your application, you can
always use the 'cmd' module: http://docs.python.org/library/cmd.html
It is present in both Python 2 and Python 3 and should just 'do the right
thing'. It also seamlessly integrates readline (if present),
command-completion, and provides a built-in help menu for defined commands.
It's written in pure Python, and in my opinion, the best form of
documentation for that module is the source code itself.
I haven't used it in Python 3, but I imagine it can be used in a way that
easily supports Python 2 and 3. If you have only one or two places where
you need user-input, this is probably overkill.
